Check the fuse and make sure it is not blown.
If that is not it, what is the model number?
There is no model 4.0FFA.
Ah, ok. I suspected it would be BFA, but there are so many similar-named models that I had to be sure.
The first thing you need to check are the 2 fuses on the front control panel. Make sure neither one of them are blown, particularly the F1 fuse. Do not rely on a visual inspection - use an ohmmeter or continuity tester to actually test them.
If the fuses are good, test to make sure you have good 12V to the large post of the starter solenoid inside the control box.
If you do not, you have a battery or battery cable issue.
If this does not find the problem, let me know.
